Precautions for Correct Use
• The maximum total length of Ethernet Cable is 100 m.
• The maximum total length of Power Supply Cable is 60 m.
• Ask your OMRON representative for the recommended extension cables for the Ethernet
Cable and Power Supply Cable.
Precautions for Safe Use
• Connect the Ethernet Cable to a host device (e.g., Switching Hub or PLC) that supports STP
(shielded twisted-pair) and ground the host device to a ground resistance of 100
Ω
or less.
Precautions for Correct Use
If you loop the Ethernet line, one broadcast packet may consume the entire bandwidth, pre-
venting communications or possibly causing the Reader/Writer to stop operation. Do not create
a loop in the Ethernet line when you connect it.
Also, if a large volume of broadcast packets or multicast packets are placed on the network, the
Reader/Writer’s response speed will drop and the Reader/Writer may even stop operating. Do
not place a large volume of packets on the network in this way. Also, separate segments for the
Reader/Writer from broadcast or multicast packets.
